Title:
SOUND FIELD SIMULATION METHOD AND DEVICE THEREOF
Document Type and Number:
Japanese Patent JP3115548
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To enable physical experience to be acquired for a rotational motion of a three-dimensional swing so as to instruct deflection of an instantaneous swing motion by giving a feeling by which a player has a perception as if a virtual sound source placed in a club head is moved along a three-dimensional rotation route during a series of golf swinging motion.
SOLUTION: Inside a memory 14, sound field information recorded by a binaural system is stored, and the sound field information is reproduced from a pair of speakers 19A, 19B on the left and right sides, so that sound field simulation in which a virtual sound source seems to be rotationally moved three-dimensionally is demonstrated. That is, in a microcomputer 15, the sound field information stored in the memory 14 is read while a reproduction speed is decided on the basis of a reproduction speed control signal from a reproduction speed converter 13, and the sound field information read from the memory 14 is used for sounding the headphone speakers 19A, 19B on the left and right sides via D/A converters 16A, 16B, sound volume adjusters 17A, 17B, and amplifiers 18A, 18B on the left and right sides.
